摘要： A method and system for attaching a title key to encrypted content for synchronized transmission to, or storage by, a recipient is provided. Specifically, under the present invention, an elementary media stream is parceled into content units that each include a content packet and a header. The content packets are encrypted with one or more title keys. Once the content packets have been encrypted, the title keys are themselves encrypted with a key encrypting key. The encrypted title keys are then attached to the corresponding encrypted content packets for synchronized transmission to a recipient.

摘要： Techniques are provided for re-mapping and interleaving transport packets of multiple transport streams for processing by a single transport demultiplexor. At least one PID re-map table is employed having re-map values indexed by n possible PID values of transport packets associated with at one transport stream of the multiple transport streams. The n possible PID values is less than or equal to the number of PID values which can be handled by the single transport demultiplexor, and is less than all possible PID values of transport packets within the multiple transport streams. The PID values within at least one transport stream are compared with the n possible PID values of the PID re-map table, and when a match is found, the table is indexed using the matching entry and a re-map value is generated therefrom. The re-map value replaces the original PID value within the transport packet.

摘要： Cross-bar segment routing and access table address remapping functions are combined within a cross-bar of a system-on-a-chip. In this manner, address remapping may occur prior to segment routing. One or more access table caching registers may be included for each master port. The caching registers may allow for a rapid lookup of one or more access table entries associated with each master, as well as allow for the simultaneous lookup by multiple masters without adding ports to the access table. A segment identifier may be stored in the caching registers to indicate how to route a matching request to the appropriate slave segment.

摘要： The preferred embodiment of the present invention provides an improved transport demultiplexor that can receive and filter different data types before sending the data to system memory. The preferred embodiment provides a string comparator to facilitate real time filtering of continuous incoming data before loading the data into system memory. The string comparator preferably uses a bit-maskable matching filter that filters system data in real time as the data is being delivered to system memory. When data matching the filter is located, the destination address of that data is determined and delivered to the processor. This allows the processor to quickly locate the desired data and thus facilitates the real time processing of that data.

摘要： Method, system and computer products are provided for re-mapping and interleaving transport packets of multiple transport streams for processing by a single transport demultiplexor. The re-mapping and interleaving technique ensures unique identification of transport packets associated with multiple transport streams to be multiplexed onto a transport channel for demultiplexing by a single transport demultiplexor. At least one PID re-map table is employed having re-map values indexed by n possible PID values of transport packets associated with at one transport stream of the multiple transport streams. The n possible PID values is less than or equal to the number of PID values which can be handled by the single transport demultiplexor, and is less than all possible PID values of transport packets within the multiple transport streams. The PID values of transport packets within at least one transport stream are compared with the n possible PID values of the PID re-map table, and when a match is found, the table is indexed using the matching entry and a re-map value is generated therefrom. The re-map value replaces the original PID value within the transport packet to be forwarded for interleaving.

摘要： An access control function for an integrated system is provided which determines data access based on the master id of a requesting master within the system and the address of the data. The access control function can be inserted, for example, into the data transfer path between bus control logic and one or more slaves. In addition to determining whether to grant access to the data, the access control function can further qualify the access by selectively implementing encryption and decryption of data, again dependent on the data authorization level for the particular functional master initiating the request for data.

摘要： A device and method are provided for merging one or more secondary audio channels, received from either a streaming application or from memory, with a primary stream of audio data output from a main audio decoder. In addition to the audio decoder, the device/method employs a controller for processing received secondary audio data in a streaming application, and retrieving from system memory audio PCM data once stored. An audio playback device is provided for formatting the PCM data for mixing with the primary stream of audio data output from the audio decoder. Multiple digital-to-analog converters convert the multiple streams of audio data into analog signals which are then mixed into a single merged audio signal for presentation.

摘要： A data authentication technique is provided for a data access control function of an integrated system. The technique includes passing a data request from a functional master of the integrated system through the data access control function, and responsive to the data request, selectively authenticating requested data. The selective authentication, which can occur transparent to the functional master initiating the data request, includes employing integrity value generation on the requested data when originally stored and when retrieved, in combination with encryption and decryption thereof to ensure the authenticity of the requested data. As an enhancement, cascading integrity values may be employed to facilitate data authentication.

摘要： A transport demultiplexor system and queue remultiplexing methodology includes: a packet buffer for receiving data packets belonging to an input transport stream, each packet having a corresponding identifier identifying a program to which the packet belongs; a data unloader device for pulling successive packets from the packet buffer for storage in a memory storage device, and writing the pulled packets into contiguous address locations in the memory; and, a remultiplexor mechanism for generating an address offset associated with a next data packet pulled from the packet buffer to be stored in memory and writing it to a new memory location that is offset from a memory location assigned to a previously pulled packet, the offset defining a memory gap in the memory storage device capable of being filled new data content.
